摘要

摘要
4-苯基二苯甲酮(PBP)在480nm~512nm波長範圍生命期為32μs的結構性磷光在苯溶劑中受到三乙胺，2-庚胺及十二烷胺的淬熄作用，在648nm處生成一個無結構性的激合體放射光譜其生命期分別為40μs,
53μs,46μs, 由淬熄作用的機制來看，其648nm處的放射峰可能由激發參重態(π,π*)3 和(n,π*)3的PBP與基態的三乙胺，2-庚胺及十二烷胺所形成

Abstract:
Structured phosophorescence with 32μs life time [480nm, 510nm(max),] from 4-phenyl-benzophenone(4-PBP) was quenched
by triethylamine (TEA) and2-heptylamine( 2-HPA),
dodecylamine(DDA) in benzene,respectively. An exciplex emission with strutureless 40μs,53μs,46μs life time peaking at 648nm. A quenching mechanism has been proposed to involve a mixed (π,π*)and (n,π*) triplet of 4- PBP to form an exciplex with the ground state of TEA , 2-HPA and DDA ,respectively.
