group shows regular influence on the 10Dq values as 10Dq (O) > 10Dq (N) > 10Dq (S), which reflects the σ-donor/π-acceptor properties of these benzazole ligands. Upon activation with modified methylaluminoxane (MMAO), these complexes exhibited high activities for ethylene oligomerization (up to 7.36 × 106 g mol−1 (Cr) h−1) and ethylenepolymerization (up to 1.28 × 106 g mol−1 (Cr) h−1). The effects of
