Speaker: Dr. Malika Jeffries-EL

Date: Friday February 3, 2017

Location: Lash Miller Chemical Laboratories, LM158

Abstract: Since their discovery over 40 years ago conjugated polymers have been of tremendous scientific and technological interest. These materials posses many exceptional electronic, optical and thermal properties and thus are well suited for organic semiconducting applications, such as solar cells and light emitting diodes. Unfortunately, there are several issues that have to be addressed before real-life products can be developed. Our group focuses on the design and synthesis of new types of conjugated polymers based from low cost and/or easily prepared starting materials. Since the properties of organic semiconductors can be readily modified through chemical synthesis, we have turned our attention towards the design and synthesis of novel building blocks. Our system of choice, polybenzobisazoles possess many exceptional electronic, optical and thermal properties and thus are ideally suited for diverse organic semiconducting applications. However, these materials have found limited utility due their lack of solubility in organic solvents and the harsh conditions required for their synthesis. The resolve this issue, our group has developed a mild approach for the synthesis of benzobisoxazoles resulting in several building blocks suitable for designing new polymers. As a result we have been able to prepare wide band gap materials for use in organic light-emitting diodes and narrow band gap materials for use in photovoltaic cells. We have also pioneered the synthesis of benzodifuran, the oxygen analog of the popular electron rich building block benzodithiophene and are developing narrow band gap conjugated polymers based on it. Our work on the synthesis and properties
and utility of these polymers will be presented.

2015-2016


Speaker: Dr. Miriam Diamond

Date: Thursday December 15, 2016

Location: Lash Miller Chemical Laboratories, Davenport East Seminar Room (3rd floor)

Abstract: Most women experience no or minimal gender bias as they move through undergraduate and graduate school. At University of Toronto, most faculty candidates and early career faculty will have an experience free of gender bias. Have we been successful in creating an atmosphere free of gender bias at the University? Is an atmosphere free of gender-bias widespread at other universities? What do the statistics and the literature tell us about overt and subtle gender bias at universities and beyond? University of Toronto has been a leader amongst institutions in minimizing gender bias. Current statistics show 7 out of 18 divisions employ more than 40% female faculty and 9 of the remaining divisions have increased the numbers of women hired over the past 10 years. However, although women are more likely than men to be chosen for an interview, women are less likely to receive an offer. These statistics fit the “scissor” effect of attrition of women through the ranks. Recent research shows subtle gender bias by both men and women in terms of hiring and evaluation. Finally, we will explore what the future might hold. Although we have made great strides to reduce gender bias in many universities and in many parts of Canadian society, will women be able to continue to exercise self-determination in the future?

 

 

shanakelley-seminar4Speaker: Dr. Shana Kelley

Date: Tuesday November 22, 2016

Location: Lash Miller Chemical Laboratories, Davenport East Seminar Room (3rd floor)

Abstract: Our research group uses a foundation in Chemistry to develop devices and molecules that allow
biology to be studied in new ways. We exploit the interfaces of Chemistry with Materials Science, Engineering and Biology to maximize the impact of our effort, and we constantly fold new approaches into our research projects to take them in exciting directions. We use the unique properties of nanomaterials to develop ultrasensitive approaches to the detection of biomolecular analytes and rare cells, eventually turning these sensors into devices that can be used in the clinic. We also develop molecular delivery systems that can specifically bring molecular cargo to a particular part of the cells. I’ll provide an overview of these research areas, and also discuss the experience of running a research group as a female scientist.

Date & Location: Tuesday, Jan. 19th, 2016, Lash Miller Rm 158 (University of Toronto, St. George Campus)

Time: 10 a.m.

Title: How Homogeneous Are These Heterogeneous Organic Catalysts?

Abstract: The development of an efficient, convenient and recyclable catalytic system based on a supported organocatalyst is still a major challenge. The search for a green catalyst, and our interest in the synthesis of porous silica based materials prompted us to explore an alternative immobilization method, in which a chiral imidazolium salt derived from trans-L-hydroxyproline, is immobilized on the surface of mesoporous silica so that the imidazolium cation is covalently linked to the silica, but the proline anion is bound via electrostatic interactions. We suspect this allows the proline more freedom to react in the solution state, making it more available to participate in catalysis resulting in higher activity then past heterogeneous proline catalysts have shown.  We report excellent isolated yields in the aldol condensation reaction (up to 99%), as well as modest selectivities (ee up to 85%).  The stability and sustained activity of the catalyst were investigated and the results show that no loss of catalyst activity was found, even after five recoveries (washing & drying) and recycles. The NHC-based material demonstrated intriguing carbon dioxide capture ability

WICTO Sophie Rousseaux“Supramolecular Chemistry of Porphyrin Nanorings”

Speaker: Dr. Sophie Rousseaux

Abstract:
Fully pi-conjugated macrocycles have attracted significant attention due to their interesting optical and electronic properties. The Anderson group at the University of Oxford has recently prepared conjugated porphyrin nanorings using strategies that rely on molecular recognition and cooperative self-assembly. Notably, these macrocycles resemble the chlorophyll arrays in the light-harvesting antennae of natural photosynthetic systems.
