Description
Summary:•A pattern-generating molecule used for information processing (encoding-decoding) is reported.•This method involves only absorption mode and uses single threshold intensity. Hence, Expeditious.•Temopofin has ability to accept many metals as input and generate different absorption intensities as output signals. Thus, able to process multiple information by performing as various encoder and decoder.•A molecular information processing system was designed by engineering several encoding-decoding modules akin to biological and digital information processing system. Multiple chemical information processing (i.e. encoding and decoding) was achieved by a Q-band absorption pattern-generating miniaturized chromophore “temoporfin” using a set of metal inputs in various combinations akin to biological and digital information processing systems. The distinct Q-band absorption intensities gener-ated as outputs at different wavelengths employing single instrumental method enabled us to perform as several complex logic 4-to-2 encoders and 2-to-3 decoders in an expeditious manner.
