Neutral, panchromatic Ru(ii) terpyridine sensitizers bearing pyridine pyrazolate chelates with superior DSSC performance†
Abstract
A new series of neutral, panchromatic Ru(II) terpyridine sensitizers (PRT1–PRT4) exhibit much higher molar extinction coefficients at 400–550 nm and superior DSSC performance in terms of conversion efficiency (η = 10.05 for PRT4) and stability.
