Dipole moment at ground state. The absorption maximum wavelength. Blue shift of the absorption maximum wavelength (the values were calculated according to following method: of 1DMNA— of “parallel connection” chromophores.). Enhancement of of “parallel connection” chromophores compared with that of 1DMNA (the values were calculated according to following method: of chromophores containing DMNA units/ of 1DMNA). |
