1. A nanomaterial, which is a product formed by a reaction of:
a functionalized carbon nanotube comprising first and second aminoalkyl groups covalently bonded to a surface of the carbon nanotube; and
a porphyrin ring of formula (I)

or a salt thereof, a solvate thereof, a tautomer thereof, a stereoisomer thereof, a metalation product thereof, or a mixture thereof,
wherein:
the first and second aminoalkyl groups are each independently a C1-6 alkyl substituted with at least one primary or secondary amino group;
R1 and R2 are independently —COOH or an activated carbonyl group;
R3, R4, R5, R6, R7, and R8 are each independently selected from the group consisting of a hydrogen, an optionally substituted C1-6 alkyl, an optionally substituted C1-6 cycloalkyl, and an optionally substituted C1-6 alkenyl;
n1 and n2 are independently an integer in a range of 1-6; and
the functionalized carbon nanotube is bonded with the porphyrin ring of formula (I) via two amide linkages, one formed between R1 of the porphyrin ring and the first aminoalkyl group of the functionalized carbon nanotube, and the other between R2 of the porphyrin ring and the second aminoalkyl group of the functionalized carbon nanotube.
