Trying to customize the comments made by the author

I am trying to customize the comments I leave on my own blog, by calling a special division if the email left is my own, otherwise it calls the normal division. Here is the code I am using:

<?php
if($comment->comment_author_email == ‘[email protected]’){ ?>
<div class=”blogauthor”>
<?php } else { ?>
<div class=”normalcomment”>
<?php } ?>

However when i implement it I get an error on the comments saying:

“an unexpected @ was found on the comment function”

The error is obviously coming from the @ on the email I inserted.

How can I solve this?
