M is titanium (Ti), zirconium (Zr), or hafnium (Hf),
X is each independently halogen, C1-20 alkyl, C2-20 alkenyl, C2-20 alkynyl, C6-20 aryl, C1-20 alkyl C6-20 aryl, C6-20 aryl C1-20 alkyl, C1-20 alkylamido, C6-20 arylamido, or C1-20 alkylidene,
Q is carbon (C), silicon (Si), germanium (Ge), or tin (Sn),
R1, R2, R6, and R7 are each independently substituted or unsubstituted C1-20 alkyl, substituted or unsubstituted C2-20 alkenyl, substituted or unsubstituted C6-20 aryl, substituted or unsubstituted C1-20 alkyl C6-20 aryl, substituted or unsubstituted C6-20 aryl C1-20 alkyl, substituted or unsubstituted C1-20 heteroalkyl, substituted or unsubstituted C3-20 heteroaryl, substituted or unsubstituted C1-20 alkylamido, substituted or unsubstituted C6-20 arylamido, substituted or unsubstituted C1-20 alkylidene, or substituted or unsubstituted C1-20 silyl,
