These preliminary results indicate that CAPE is effective in suppressing PCO in pigmented rabbits and may be beneficial in clinical use in humans because it has no documented harmful effects on normal cells.

In this study, novel metallo-supramolecular materials based on terpyridine-functionalized polyhedral silsesquioxane were synthesized from 4 -chloro-2,2 :6 ,2 -terpyridine and amino-group-functionalized polyhedral oligomeric silsesquioxane. The obtained terpyridine-functionalized polyhedral silsesquioxanes were converted to metallo-supramolecular hybrid materials by coordination polycondensation reaction with Co(II) or Cu(II) ions. The supramolecular polymers created were characterized by means of structure, morphology and stimuli-responsive performance employing scanning electron microscopy, amperometric techniques and UV-visible and Fourier transform IR spectroscopy. UV−visible and cyclic voltammetry studies showed that both the optical and electrochemical properties of metallo-supramolecular materials are affected by the substituent at the pyridine periphery. The supramolecular polymers obtained exhibited electrochromism during the oxidation processes of cyclic voltammogram studies. As a result, these terpyridine-functionalized polyhedral silsesquioxanes are good candidates for electronic, opto-electronic and photovoltaic applications as smart stimuli-responsive materials.
