draken怎么读CRC1RC2-NRN1, where RC1, RC2 and RN1 are independently lected from H, halo, optionally substituted C1-20 alkyl, optionally substituted C5-20 aryl, ether and nitro; each of the substituents R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, and R16, is independently lected from H, halo, optionally substituted C1-20 alkyl, optionally substituted C5-20 aryl, optionally substituted C3-20 heterocyclyl, ether and nitro; X1 and X2 are independently either (i) a C2-5 alkylene chain, which is optionally substituted by one or more groups lected from C1-4 alkyl and C5-7 aryl, or a C1-3 bisoxyalkylene chain, which is optionally substituted by one or more groups lected from C1-4 alkyl and C5-7 aryl or (ii) reprent a divalent group lected from C5-7 arylene, C5-7 cyclic alkylene and C3-7 heterocyclylene, which may be optionally substituted; (i) (a) at least one of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, and R16 is lected from L-A, where L is a single bond or a C1-10 alkylene group and A is an ammonium group paired with a counterion lected from Cl, Br and I; and/or (b) at least one of X1 and X2 is a divalent C3-7 heterocyclene group, containing a ring atom which is a quaternary nitrogen atom paired with a counterion lected from Cl, Br and I; and/or (c) at least one of X1 and X2 is a C2-5 alkylene chain or a C1-3 bisoxyalkylene chain,
substituted by a group -Q-L-A, where Q is either -C(=O)-O-, -C(=O)-NH-, or a single bond; and/or (ii) (a) one of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, and R16 is L-A', where L is as defined above and A' is a ammonium linking group bound to a solid support and paired with a counterion lected from Cl, Br and I; or (b) one of X1 and X2 is a divalent C3-7 heterocyclene group, containing a ring atom which is a quaternary nitrogen forming part of an ammonium linking group bound to a solid support and paired with a counterion lected from Cl, Br and I; or (c) one of X1 and X2 is a C2-5 alkylene chain or a C1-3 bisoxyalkylene chain, substituted by a group -Q-L-A'.
