Product Usage

2,3,3,4-biphenyl tetracarboxylic dianhydride (a-BPDA) and polyamides (PAA) derived from p-phenylenediamine (PDA) or 4,4'-oxydiphenylamine (ODA) undergo thermal imidisation and can be used for the preparation of asymmetric biphenyl-type polyimides (PI). Compared to the semi-rigid s-BPDA/PDA, the a-BPDA/PDA polyimides have a significantly bent chain structure. However, a-BPDA/PDA films annealed at 350 °C show higher Tg than s-BPDA/PDA films prepared under the same conditions. a-BPDA-based PIs have unexpectedly high Tg values, which may be attributed to the cranked axial motion limiting conformational changes. The diimide synthesised from a-BPDA and cyclohexylamine displays long-lived luminescence of up to 1.3 s after UV irradiation.
