Abstract

D. C. Neckers, a photoscientist, started the Center for Photochemical Sciences at Bowling Green State University (OHIO, USA ) in 1985. The Center now houses one of the few Ph. D. programs in the photosciences in the world. As of last July, 17 faculty from four departments were part of the Center, and ≈ 60 full time Ph.D. students were enrolled in Center programs. Neckers research interests are in photopolymerization, photpolymer science, imaging and stereolithography. He, his students and his post-doctorals have published about 400 papers in refereed journals, and he holds approximately 50 US patents. His discussion in today’s seminar will focus on the elusive group of aromatic compounds known as the poly(acenes). .. i. e. benzene, naphthalene, anthracene, tetracene, pentacene, hexacene, heptacene …[octacene], [nonacene] .... ... poly(acene)s. As of this date, heptacene has been synthesized in matrices only (to be discussed) while octacene and nonacene are unknown.
