series of merocyanine dyes with excellent spectral properties were synthesized through changing the heterocyclic base structure for protein labeling and imaging in biological science, such as living cells and living mice. Dyes 7c–7h showed solvent-dependent changes on emission wavelength and fluorescence intensity in water and hydrophobic solvents, which were further analyzed by theoretical calculations
