OG Complex Work Unit Drawing
wherein A1 and A2 are each independently a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted aryl group having 5 to 50 nuclear carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 20 nuclear carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 10 carbon atoms, a substituted or unsubstituted aryloxy group having 5 to 50 nuclear carbon atoms, a substituted or unsubstituted arylamino group having 5 to 50 nuclear carbon atoms, a substituted or unsubstituted alkylamino group having 1 to 10 carbon atoms, or a halogen atom, with the proviso that A1 and A2 are not both hydrogen atoms, p and q are each an integer of 1 to 5, and when p or q is 2 or more, a plurality of A1 or A2 groups may be the same or different and may be bonded to each other to form a saturated or unsaturated ring;
R1 is a substituted or unsubstituted secondary or tertiary alkyl group having 3 to 10 carbon atoms, or a subsituted or unsubstituted secondary or tertiary cycloalkyl group having 3 to 10 carbon atoms;
R2 is a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted aryl group having 5 to 50 nuclear carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 20 nuclear carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 10 carbon atoms, a substituted or unsubstituted aryloxy group having 5 to 50 nucelar carbon atoms, a substituted or unsubstituted arylamino group having 5 to 50 nuclear carbon atoms, a substituted or unsubstituted alkylamino group having 1 to 10 carbon atoms, or a halogen atom.
