Reagent for enhancing generation of chemical species

A composition, comprising:

• a reagent;
• a first compound able to react with a chemical species to cause a deprotection reaction of the first compound;
• and
• a precursor,
• wherein the reagent is selected from the group consisting of a first reagent, a second reagent, and a third reagent,
• the first reagent being represented by one of formula (I),
• wherein
• R1 is a hydrogen atom;
• R2 is a phenyl group, an alkyl carbonyl group, an aryl carbonyl group, an alkyl group, an alkenyl group, an aralkyl group, an alkynyl group, an alkyl group containing a cyclic or poly cyclic moiety, or a substituent containing at least one atom other than carbon atom and hydrogen atom;
• and
• R3 is a hydrogen atom, a phenyl group, an alkyl carbonyl group, an aryl carbonyl group, an alkyl group, an alkenyl group, an aralkyl group, an alkynyl group, an alkyl group containing a cyclic or poly cyclic moiety, or a substituent containing at least one atom other than carbon atom and hydrogen atom,
• the second reagent being represented by one of formula (II),
• wherein
• R1 is a hydrogen atom;
• R2 is a phenyl group, an alkyl carbonyl group, an aryl carbonyl group, an alkyl group, an alkenyl group, an aralkyl group, an alkynyl group, an alkyl group containing a cyclic or poly cyclic moiety, or a substituent containing at least one atom other than carbon atom and hydrogen atom;
• R3 is a hydrogen atom, a phenyl group, an alkyl carbonyl group, an aryl carbonyl group, an alkyl group, an alkenyl group, an aralkyl group, an alkynyl group, an alkyl group containing a cyclic or poly cyclic moiety, or a substituent containing at least one atom other than carbon atom and hydrogen atom;
• and
• R4 is a protective group for a hydroxyl group or a group containing a carbon atom;
• and
• the third reagent includes a hydroxyl group and a first cyclic moiety that contains a carbon atom bonded to the hydroxyl group and a hydrogen atom;
• wherein:
• an intermediate is generated from the reagent by a feed energy;
• the intermediate enhances a generation of the chemical species from a precursor;
• a product resulting from the intermediate has a conjugation length longer than a conjugation length of the reagent;
• wherein the feed energy is carried out by a first irradiation of the reagent or an acceptor receiving the energy with at least one of a light, the wavelength of which is shorter than or equal to 15 nm and an electron beam;
• and
• wherein the generation of the chemical species from the precursor is improved by a second irradiation with a light, the wavelength of which is longer than or equal to 300 nm.
