Charge-transfer Zn-porphyrin derivatives with very large two-photon absorption cross sections at 1.3-1.5 μm fundamental wavelengths -: art. no. 096101

A series of charge-transfer Zn-porphyrin derivatives with large two-photon absorption cross sections at 1.3-1.5 mum fundamental wavelengths are designed using time-dependent hybrid density functional theory. The fluorescence of these chromospheres is expected to be in the region of 700-900 nm. These unique features make them suitable for a variety of biophotonic and telecommunication applications.
