Here we describe the synthesis and the linear and nonlinear optical properties of three dibutylaminoazobenzenephosphonium salt chromophores: a one-dimensional system with one azobenzene subchromophore and two three-dimensional systems, one with C(3) symmetry (three subchromophores) and one with approximate T symmetry (four subchromophores). Experimental investigations (UV/Vis spectroscopy and hyper-Rayleigh scattering), theoretical calculations (exciton coupling theory and tensor transformations), as well as computational calculations (PM3/time-dependent Hartree-Fock) show that, while the linear optical properties of the 3D compounds behave additively the first-order hyperpolarisability beta is distinctly enhanced in the 3D compounds relative to the 1D derivative.
