- Abstract
- New blue photoluminescent materials 4,4'-bis(1-naphthyl)-2,2'-bithiazole (BNBT) and 4,4'-bis(4-biphenyl)-2,2'-bithiazole (BPBT) were synthesized by the facile reaction of 2-bromoacetoaromatic compound with dithioxamide. The resulting BNBT and BPBT having thiazole moiety were characterized by NMR, infrared (IR), UV/visible absorption and are well vacuum deposited for thin films. The BNBT and BPBT show blue photoluminescent (PL) spectra at 437 and 432 nm, respectively, and typical rectifying diode characteristics in ITO/BNBT or BPBT/Al device. The BNBT and BPBT are thermally stable up to 330 degrees C and 360 degrees C, respectively, under N-2. (c) 2001 Elsevier Science B.V. All rights reserved.
