TL;DR: In this article, a review of colorless and optically transparent polyimide (CPI) films has been presented, focusing on the applications of CPI films as flexible substrates for optoelectrical devices, such as flexible active matrix organic light emitting display devices (AMOLEDs), flexible printing circuit boards (FPCBs), and flexible solar cells.

TL;DR: In this paper, a series of highly fluorinated polyimides were synthesized, which exhibited good thermal stability with the glass transition temperature (Tg) of 209-239°C and outstanding mechanical properties with the tensile strengths of 88-111 MPa and tensile modulus of 2.65-3.17 GPa.

TL;DR: In this paper, a meta- substituted aromatic diamine containing trifluoromethyl and sulfonyl groups in the backbone was synthesized and characterized, and a series of semi-aromatic polyimides were prepared from 1,2,4,5-cyclohexanetetetracarboxylic dianhydride (CHDA) and various aromatic diamines.

TL;DR: In this paper, a novel imide ring and siloxane-containing cycloaliphatic epoxy compound 1,3-bis[3-(4,5-epoxy-1,2,3,6-tetrahydrophthalimido)propyl]tetramethyldisiloxane (BISE) was synthesized from 1, 3-bis(3-aminopropyl)tetrameryl)trimethyl-methyl-3′,4′-EPoxycyclohexane carboxylate

TL;DR: In this article, a new diamine monomer containing pyridine unit, 2,6-Bis(3-aminobenzoyl)pyridine (BABP), was synthesized by the Friedel-Crafts acylation of benzene with 2, 6-pyridinedicarbonyl chloride to form 2,Dibenzoylpyridine, and the nitrification of DBPY with nitric acid (99%) to form dinitro compound (BNBP), and the deoxidization of BNBP using
