spectroscopic ellipsometry. The anilino squaraine coalesces and readily aggregates to circulardichroic but discontinuous thin films. The extent of circular dichroism correlates with the morphology of the samples, which is quantified by Mueller matrix polarimetry in combination with atomic force microscopy. The shape of the CD spectra reinforces the hybrid Frenkel and charge-transfer excitonic nature of the characteristic

squaric acid moiety, through a modified squaric acid unit where a vinyl dicyano group has replaced one carbonyl, via an alkyl carboxylate attached to the indole N or through a carboxylate attached to the 4 position of a benzyl indole. Contact angle measurements have been studied to investigate the hydrophobic/hydrophilic properties of the dyes and the results have been compared to N719 and Z907. Full characterization

unsymmetrical red emitting squaraine dyes is reported, varying the substituents to modulate the hydrophilic/hydrophobic ratio of the fluorescentprobes. Their ability to stain cellular membranes is assessed by studying their interactions with liposomal model systems, screening the key features for the design of squaraine-based cell membrane probes.
