• (model: C9920-02G), respectively. Solution emission spectra were attained for samples dissolved in dichloromethane with a FluoroMax 2 spectrometer. For microscopy a WiTec AlphaSNOM was used for wide-field images and a Veeco scanning probe microscope (SPM) was used in tapping mode for atomic force
