Synthesis and evaluation of photophysical properties of Series of π-conjugated oxazole dyes
摘要:
Incorporation of pi-conjugated spacers at the 2 or 5 position of a 2,5-disubstitutedaryloxazole led to new series of fluorescent dyes. They show emissions from visible to 700 nm along with significant Stokes shift up to 208 nm and a strong solvatochromic fluorescence. These compounds are easily accessible in one step through direct C-H bond functionalization. (C) 2013 Elsevier Ltd. All rights reserved.

(i–PrPCP)IrH2 is found to be a remarkably effective solution-phase catalyst for the ‘acceptorless’ thermochemical dehydrogenation of cycloalkanes (and isomerization in the case of cyclodecane), and the first such catalyst reported to effect the dehydrogenation of n-alkanes.
