- q=1-230;
- T, T′ independently=O(CH2)d′, NH(CH2)d′, NCH3(CH2)d′, O(CH2)d′C6H4, O(CH2CH2O)d′CH2, O(CH2CH2CH2O)d′CH2, O(CH2CH2CH2CH2O)d′CH2, or nothing;
- K=(CH2)a′, O(CH2CH2O)b′, O, or nothing, provided that if T and T′=nothing, then K≠nothing;
- d′=0-12;
- a′=1-12;
- b′=1-24;
- L=H, Cl, Br, —CH2C(O)CH3, CH2C(O)C(CH3)3, —CH2C(O)C6H5, —CH2C(O)C6H4OH, —CH2C(O)C6H4OCH3,

- L=H, Cl, Br, —CH2C(O)CH3, CH2C(O)C(CH3)3, —CH2C(O)C6H5, —CH2C(O)C6H4OH, —CH2C(O)C6H4OCH3,
- or
- —CH2CH═CH2;
- R4, R5 independently=H, CH3, CH2CH3, CH2CH2CH3, CH(CH3)2, CH2CH2CH2CH3, or CH2CH(CH3)2;
