Synthesis and optical recording properties of some novel styryl dyes for DVD-R

摘要

The synthesis and spectral properties of styryl dyes 6a-6d, having julolidinyl derivative moieties at one side of the styryl dye structure, are described. These dyes are designed to have different side groups with either carbonate, ether or sulfonate linkages on the julolidinyl ring. Differences in optical, thermal and optical recording properties between these dyes have been compared. The relationships between the side groups and optical/thermal properties of the dyes are discussed.
