Bonus

Phthalo·cyanines are a macrocycle family with many practical applications. For 10 points each:
[10m] A phthalocyanine complexed with this metal is a promising candidate for an efficient organic solar cell due to its high electron exchange rate. This transition metal is found in Benedict’s reagent and Gilman reagents.
ANSWER: copper [accept copper phthalocyanine; accept copper sulfate]
[10h] IBM Research has investigated the possibility of using naphthalo·cyanine as a stand-alone example of these systems. One example of these systems used the quenching of a metal ion–accepting crown ether to transfer energy to anthracene, causing it to fluoresce.
ANSWER: molecular logic gates [accept molecular switches; prompt on gates or logic gates] (De Silva et al.’s early version of a molecular AND gate utilized a benzo-18-crown-6 unit bound to an anthracene.)
[10e] Silicon phthalocyanine belongs to a class of “sensitizers” that pass energy from these particles to other molecules. These particles are the quanta of light.
ANSWER: photons [prompt on photosensitizers]
