摘要：

ESR studies have been made on the supersensitization of naphthothiacarbocyanine (NTCC) by some holopolar trinuclear cyanine dyes (TNC). It was found that some allopolar trinuclear cyanine dyes containing an acidic nucleus [GRAPHICS] (existing in holopolar form) can supersensitize NTCC very well; there is good correlation between DELTAI(ESR) and increase in the AS value. These results support the general conclusion that a positive hole produced by the sensitizer is trapped by the supersensitizer.
