,15-Bis(mesity)-10,20-bis(4-amino)porphyrin was synthesized with meso-(mesityl)dipyrromethane and 4-nitrobenzaldehyde. It was characterized with1H-NMR spectroscopy, UV spectrophotometer, and GC-MASS. In UV spectrum, Soret-band(438 nm) and Q-bands(526, 572, 611 nm) were confirmed. In NMR spectrum, the characteristic peak of porphyrin was detected at -2.65 ppm. Copolyimide containing porphyrin structure was synthesized with mesityl-TPP(NH2), 3,3`,4,4`-benzophenonetetracarboxylic dianhydride(BTDA) and 2,2-bis(4-(4-aminophenoxy)phenyl) hexafluoropropane(BAPHF) and characterized with UV and FT-IR spectrophotometer. The Tgand Tmof the synthesized copolyimide were 220.7 and 369.2 ℃, respectively.

Meso-(mesityl)dipyrromethane(MS-DPM)과 4-nitrobenaldehyde로부터 5,15-bis(mesityl)-10,20-bis(4-amino)porphyrin[mesityl-TPP(NH2)]을 합성하였다. Mesityl-TPP(NH2)는 UV spectrophotometer[Soret-band(438 nm), Q-band(526, 572, 611 nm)]와1H-NMR spectroscopy에 의해 그 구조를 확인하였다. 3,3`,4,4`-Benzophenone tetracarboxylic dianhydride(BTDA)와 2,2-bis(4-(4-aminophenoxy)-phenyl)hexafluoropropane(BAPHF)를 mesityl-TPP(NH2)와 축합시켜 porphyrin 구조를 포함하는 copolyimide를 합성하였다. 제조된 copolyimide 역시 UV spectrophotometer [Soret-band (428 nm), Q-band (558 nm, 599 nm)]와 FT-IR spectrophotometer를 이용하여 그 구조를 확인하였고, 열분석 결과 Tg와 Tm은 각각 220.7와 369.2℃였다.
