Abstract

This paper presents a sustainable approach to creating photonics bioplastics by integrating triplet–triplet annihilation photon upconversion crystals with bacterial cellulose. Pd(II) meso-tetraphenyl tetrabenzoporphine: 9,10-diphenyl anthracene crystals are cultivated on bacterial cellulose, creating a photon-upconverting biomaterial. Gelatin coating enhances optical transparency. The resulting material upconverts red light to blue light, exhibiting nonlinear behavior. Importantly, the material is physically disassembled for chromophore recycling, achieving 66 ± 1% recovery, with the remaining biomass biodegradable.
