High electric conductivity exceeding $10^{-2}$ S/cm was observed in a co-deposited film of 1,4,5,8-naphthalene-tetracarboxylic-dianhydride (NTCDA) and indium, exhibiting electronic interaction characterized by remarkable changes of electronic absorption and electron spin resonance (ESR). The increase of conductivity was attributed to charge transfer from indium to the carbonyl oxygen of NTCDA, and therefore, was strongly dependent on the chemical structure of organic molecules. This result suggests a new guiding principle of chemical doping in low-molecular semiconductors, utilizing chemical interactions peculiar to the combination of molecules and metals.
