Paper Abstract

Recently, donor-acceptor substituted methine chromophores with a large figure-of-merit for incorporation into photorefractive polymers with low glass-transition temperature have become available. However, their rather polar nature lead to aggregate formation and dipole cancellation, thus limiting their use in typical non-polar photoconducting matrices. By increasing the polarity of the matrix we were able to overcome this problem. The material we report shows unprecedented performance compared to previously known materials, is sufficiently resistant against phase separation, and operates in the NIR at typical wavelengths of commercially available high-power laser diodes.
