AbstractThis study proposes a molecular design and synthetic route to novel colorless, transparent polyimides that exhibit dual fluorescence/phosphorescence emission at long wavelengths applicable to solar energy conversion. Partially alicyclic polyimides (Ac-PI-TBs) based on Trager's base (TB) and denoted as Ac-PI-TB-1, Ac-PI-TB-2, and Ac-PI-TB-3 were synthesized by in situ TB formation. The resulting Ac-PI-TBs are readily soluble in common organic solvents and have good mechanical properties with tensile strengths of 72.5-102.3 MPa, elongations at breaks of 12.5-75.0%, low dielectric constants (similar to 2.66) and low thermal diffusivities (D-perpendicular to <= 7.7 X 10(-8) m(2)/s), and good thermal stability. The films are totally colorless and transparent with transmittances above 77% at 400 nm. The films also show dual fluorescence and phosphorescence emissions with Stokes shifts as large as 11 421 cm(-1) at low temperatures. The results highlight the possible application of these films in the spectral conversion of unused UV solar radiation to useful visible light.
