TITLE:                    “Luminescent Gold(I) Alkynyl Compounds”

ABSTRACT:           

Taryn Forster

Gold(I) alkynyl complexes are a relatively new class of compounds that have desirable luminescent properties.¹  Upon excitation, phosphorescence is typically observed via relaxation from the triplet excited state as the heavy atom effect promotes intersystem crossing.  These compounds are extremely sensitive to small perturbations in their environment, altering the absorption and emission wavelengths in the UV-visible region, making them ideal candidates for a variety of uses including molecular recognition, optical switches, catalysis, therapeutics, and electronic applications.  This presentation will introduce the different types of gold(I) alkynyls followed by a description of their applications.
