An electrochromic apparatus comprises a first electrode layer and a second electrode layer spaced from and disposed substantially parallel to the first electrode. An electrochromic layer is disposed between the first and second electrode layers. An electrolyte layer is disposed between the electrochromic layer and one of the electrode layers. The electrochromic layer comprises the dehydration reaction product of a hydrolyzed aromatic component. An electrochromic composition comprises an aromatic component having an aromatic core and at least two silicon-based groups pending from the aromatic core. The silicon-based groups have a silicon-bonded group selected from the group of hydrolyzable groups, hydrolyzates of hydrolyzable groups, and combinations thereof. The thickness of the electrochromic layer may be minimized while achieving desirable electrochromic properties that are typically characteristic of thicker electrochromic layers, thereby imparting the electrochromic apparatus with excellent versatility and flexibility.
